Assessment of heavy metal contamination and water quality in an urban river from Argentina

The River Kali is an important surface water body in the western Uttar Pradesh (U.P). It is an intermittent river which flows throughout the monsoonal months. The present study aims to assess the heavy metal contamination in the river Kali using pollution index (PI), based on five heavy metals (Fe, Zn, Cd, Pb, and Cr) during pre and post monsoon seasons in the year 2014. The PI evaluated during pre and post monsoon seasons with respect to drinking water quality standards was found as 5.04 and 7.08 respectively, while related to inland water quality standards were found as 4.37 and 3.62, respectively. The results indicate that the river Kali was severely contaminated (PI>3) in both seasons. Therefore, water of Kali River is not fit for drinking as well as for agriculture purposes.

Abstract. Heavy metal contamination is a major threat for marine ecosystem that directly affecting the organisms’ life. Some of marine organisms have an ability to response the heavy metal contamination in water, and could be used as bio-indicator. One of them is seagrass that used in this study to evaluate the water quality in Sanur beach. This study was held in Sanur beach, Denpasar, from July-August 2018. Sampling location determined by purposive sampling method and generated 4 research stations. Sediments and seagrass leaves (Enhalus acoroides) was collected and analyzed in Analytical Laboratory Udayana University using ICPE-9000. Water quality parameters measured in situ (temperature and salinity) and in Medical Laboratory Bali Province (pH and DO). The results showed if the water quality in all research stations were in safety range based on Governor Regulation No. 16 of 2016 about marine water quality for tourism and recreation. The highest content of heavy metal (Pb) in sediment is 16.207 mg kg-1 that possessed by the 1st station, while the lowest is 14.318 mg kg-1 at the 3rd station. The highest Pb content in seagrass leaves at the 2nd station is 5.646 mg kg-1, and the lowest at the 1st station is 4.926 mg kg-1. The 3rd station sediment had the highest Cd content is 2.252 mg kg-1 and the 4th station had the lowest is 2.044 mg kg-1, while for leaves with the highest Cd content was at the 4th station is 0.552 mg kg-1 and the lowest at the 3rd station is 0.458 mg kg-1. The Cu content in sediment was highest at the 1st station is 11.533 mg kg-1 and the lowest at the 3rd station is 8.501 mg kg-1. For leaves’ Cu content, the highest amount of Cu is 3.699 mg kg-1 at the 4th station, while the lowest at the 2nd station with 2.570 mg kg-1.
